TL;DR Review

Last season of Birdy the Mighty had very few antagonists, so to make up for it we get introduced to quite a bunch.

The animation is on par with the first season, which is overly bright scenes with an almost water-color vibe. However, around mid-season, the animation becomes very stylized during combat and action scene to the point where detail got simplified to rudimental shapes. I can’t say if this was just being lazy, trying to save cost or artistic license, but I think it’s one of the first two reasons.

The opening theme “Kiseki (奇跡,Miracle)” by Nirgilis is very cute and light in tone. I really like this song as it matches the anime theme very well. The ending theme “Tane” by no3b is also very catchy.

This season took on a faster pace and a darker tone. We also delve more into Birdy background. Though the pacing had improved since the first season, it is still rather slow compared to today standard. Despite the slower pace and the janky art style, I still enjoy this series. Its focus is more on the storytelling and character development.

I am torn between giving this a TV-14 vs TV-MA as there are some gruesome violence scenes.

I highly recommend this season to the fan of the first season. This anime contains some graphic violence and mild suggestive themes/dialogs. Intended for young adults.
